Improvement in culinary boilers

IMPROVEMENT mc 1'0 all whom it may concern 7 Be it known that I, JonNBOWLIN, oi 'Gharlestown, in the county of Middlesex and State ofMassachusetts, have invented a new and useful Improvement in Vesselsintended to housed in Heating Water, &c., or in making cofl'ee, tea, andthe like, of which the folowing is a specification: v My object is toprovide a heater which can used in connection with a kerosenelamp f or,gas-burner, as well as under other circumstances. The nature of myinvention is fully 1 described below.

- In the accompanying drawing, Figure 1 is an elevation of a vesselembodying my invention, said vessel being represented as resting I upona frame and over a kerosene-lamp, both of which are represented bybroken lines; Fig. 2is avertical section of the same, the position ofthe lamp chimney being represented by broken lines; Fig. 3 is ahorizontal section of the same in the direction and position. of theline a; a2; and Fig. 4 is a view of the strainer Y used'in making tea,cofl'ee, &c. Similar letters of reference i sponding parts. r arepresents a tea-pot or coffee-pot. bis the bail. c is the strainer, tobe used when desired. 1 d is a recess in the bottom of the vessel alarge enough to allow the chimney of a lamp to enter. 0 e e c are tubesor passages extending from the recess d through the vessel a to theoutside. These tubes are made, of course, perfectly water-tight. f f fis the inside of the vessel a, where the liquid is to 7 heat. 1 is thatportion extending down and [outside the lamp-chimney, and fis thatportionwhich extends down into the said chimney. 9 is a ,cook by meansof which water or other liquid can be drawn from the vessel a. m a o,represented by broken lines, are, respectively, a standard upon whichthe vessel a rests, a lamp, and a chimney.

In practical operation, as will readily be ndicate corre- UNITED (STATESPATENT OFFICE ,BOWLIN, OF CHARLESTOWN, MASSACHUSETTS, ASSIGNOE OF ONE.HALF HIS RIGHT TO GILES. BENNETT, OF NORTH SALEM, N. H.

ULINARV BOILERS.

Specification forming part of Letters Patent No. 133,918, dated December17,1872.

a kerosene-lamp, as seen in Fig. 1, the heat from the flame passes upthe chimney 0 into the recess (1, and, after heating quickly theprojecting parts f j f passes up and out through the tubes 0 c e c. Itwill be seen, therefore, that there is no large space which is notdirectly heated by some portion of the vessel or tubes.

In large vessels, or those of difi'erent shapes, connecting-tubes couldbe carried from f to j, or from one tube e to another.

I do not confine myself to a tea or coffee pot in which are placed thetubes above described neither do I confine myself to a vessel of anyparticular shape, size, or material. Any kind of liquid may be heated invessels thus ar ranged, and vessels useful to barbers, in hospitals,sick rooms, refreshment saloons, &c., can be readily made with myimprovement.

By means of the strainer, tea and cofl'ee can be made over a lamp asquickly as upon a stove. I

By arrangin g a suitable frame a gas-burner can be brought into use, theflame being in the recess d.

A vessel could be made for use upon a stove, if desired, without therecess 01, and having the tubes extend to the flat bottom.

The advantages of being able to heat water, make tea, &c., in families,boarding-houses, &c.,- without using a stove, especially in the summerseason, are too obvious to need comment.

what I claim, and desire to secure by Letters Patent, isa Thecombination and arrangementoi the vessel a, or its equivalent, theportions f f f, the recess d, and tubes e e e 0, arranged andconstructed substantially as and for the purposes hereinbeforedescribed.
